I gave a try with PoPoRoGue (Japan) (v1.0) and PoPoRoGue (Japan) (Yokokuban).
While dumps checksums match, i'm getting different results for this part :

There are 3 patterns in Anti-modchip screen.

Red hand version is adopted to IQ Final Taikenban and PoPoRoGue. (Only 2? I'm not sure.)

Perhaps DIC can't detect the red hand version yet.

Thanks for your input and your work on DIC while i'm at it !
How about the different EDC results ?

Doesn't crash anymore with my USB PX-755UF.

I confirm, it also doesn't crash anymore with PX-760A connected via Ugreen IDE-USB3 adapter.

It still doesn't run with Windows XP though...

For the EDC check, the current code sees if there are any missing EDC instances as per the DIC output and then if there are, it says it doesn't have EDC. If this is inaccurate, how many missing instances are needed before saying a disc doesn't have EDC? Is it if the sector count matches the error count? Or is it lower, like 300?

Bump on that EDC question, what's a good identifier from DIC outputs to see if there's EDC or not?

You can basically check only a few sectors or scan the entire data track.
For the second one, if all sectors have EDC bytes set to '00' its a NO EDC.
You can subtract 150 postgap sectors, as they can have EDC bytes set no matter what.

Also, only check MODE2 FORM1 sectors, *corrected*

Due to *cough* programmer error, we now have an updated check for EDC in a Git branch.

@sarami or @Square: do either of you know how to detect that "red hand" antimod screen? I'd like to see if I can get that working in part of DICUI.

I have no idea.

All i know is that PoPoRoGue (Japan) (v1.0) (SCPS 10050) uses the Red hand version

While PoPoRoGue (Japan) (v1.1) (SCPS 91312 / PSone Books version) use the other one.


I verified it on a 1002 equipped with a 1st gen modchip

Maybe someone with the required skills could check and compare both versions to see what has been changed ?
